Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed September 13, 1913. Serial No. 789,720.

To all whom it may concern:

Be it known that I, GEORGE R. JOUGHINS, a citizen of the British Empire, residing in Moncton, in the Province of New Brunswick, Dominion of Canada, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification The invention relates to metal car roofs, and more particularly to the shape of the metal roof sheet whereby it is provided with water-deflecting and conducting parts and gutterways, which also greatly stiffen the sheet; and the invention. further relates to combinations of such sheets with the roof sheet supporting elements of the car roof frame; and the invention consists in the parts and combinations thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical efi'ect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of example, have been delineated;

In the said drawings :Figure 1 is a transverse vertical section of a portion of a freight car roof embodying the invention, as applied in an inside metal car roof. Fig. 2 is a side view of the same partly broken away and partly in section. Fig. 3 is a plan view of one of the sheets formed with wator-deflecting projections or embossments of oblong form. Fig. 4 is a perspective View of a portion of the roof sheet shown in Fig. 3, on a larger scale, and showing also parts of the roof frame elements. Fig. 5 is a plan View, the sheet being formedwith round embossments, and with a single gutter. Fig. 6 is a perspective view showing the sheet without embossments and formed with another form of single gutter.

Referring to. the drawings, 1 indicates the ridge pole of a freight car roof; 2the side plates; 3, 4 the carlines; 5 the purlins; 6 the sub-purlins; 7 the top sheathing; 8 the inner fascia; 9 the spacingblocks; 10 the outer fascia and 11 the metalroof sheets. The

side sheathing is shown at 19. The ridge pole isformed with lateral grooves-12 into whlch the inner ends 'of the carlines enter,

, which grooves are made of suflicient height to receive also the ridge ends of the roof sheets 11. 1 The roof sheets extend over and rest at their middle portions on the alternate carlines a, and at their side edges enter grooves 13 formed in the other alternate carlines 3. The said edges of the sheets are formed with upwardly inclined flanges 14: which enter the said grooves 13, and the grooves have or may have the same inolination. The sheet is bent a little downward, from its middle toward its sides, so that its two sides or halves decline from the top of the carline 4 toward the lower part of the carlines 3. I

At or near the flange 14 and between the same and the conterminous half of the sheet there is formed a gutter 15 running from the ridge to the eaves of the car. Such gutter may be bounded at its other side by a wall 16 which extends up to about the level of the main part of the sheet (Fig. 5) but in Fig. 6 is shown a form of sheet in which the gutter is produced at the angle between V the flange la and the main part of the sheet. The gutter may be double, as shown in Figs. 2, 3 and 4:, thus insuring against any water reaching the joints at l3, l4; and also greatly stiffening the side borders of the sheets.

The main portions of the sheets may be plane, as shown in Figs. 2 and 6. Preferably, however, they are formed with embossments to stiffen them and aid in deflecting water more directly to the gutters. In Figs. 3 and 4: such embossments are shown at 17 of'oblong form, those at the middle of the sheet extending across the carline 4 and the others being inclined at an angle downward toward the gutters and toward the caves of the car. The embossments 17 are also arranged to lap a little past one another, so that water escaping from the lower end of one embossmentwill be caught on the upper end of the next and thereby deflected towardthe gutter rather than to-' and the said lapping arrangement enables 5 runways for Water, such runways being arranged diagonally across or partly across- The said runways may, be coneach plate. tinuous or may not be continuous, depending. upon the form or shape of the embossments, which may be of various forms. A circular orhemispherical form of embossment is shown at 18 in Fig. 5. Thesaidideflec- V tion of the water is aided by the fact that 7 one half of each roof sheet pitches two ways,

toward the gutter (longitudinally of the 7 car). as well as from the ridge to the eaves of thereof.- 7 1 i I V 7 The water isdelivered by the gutters at theeaves of the'car,- .over the inner fascia and through the space between the. two
